因存放时间较长、位置移动、环境变化或为获得精确测量,天平在使用前一般都应进行校准操作。虽然影响天平称量不准确的因素很多,但是如果操作人员能够做到在使用前校准天平,就可以避免外界环境因素对天平的影响而进一步得到准确的称量结果,在此建议使用者每次称量特别是开启电子天平时应对天平进行校准。一、电子天平的传感器传感器部分即机械部分是电子 Balances should generally be calibrated prior to use due to long periods of storage, changes in location, environmental changes, or for accurate measurements. Although there are many factors that affect weighing inaccurate balance, if the operator can calibrate the balance before use, you can avoid the impact of the external environmental factors on the balance and get more accurate weighing results. Weighing scales should be calibrated especially when turning on the electronic balance. First, the electronic balance sensor The sensor part of the mechanical part of the electronic
